The pupils' size change in response to the degree of light that is entering the. Dilation depends less on the distance of the object from the eye and more on how many light rays are in the field of vision.
The lens of the eye is a transparent convex body that focuses light rays entering the pupil onto the retina at the back of the eye. Its shape can be adjusted to bring objects into sharp focus through a process called accommodation.
you see with your pupil.
An Argyll Robertson pupil is a bilateral small pupil of the eye which reduces in size when the patient focuses on a near object but does not constrict when exposed to bright light - a sign of neurosyphilis.
During accommodation, the ciliary muscle contracts to change the shape of the lens, making it thicker to focus on close objects and thinner to focus on distant objects. The pupil constricts to reduce the amount of light entering the eye, enhancing focus. These changes help the eye to adjust and focus on objects at different distances.
the pupil focuses the light from the source to the eye and the darker it is, the more it has to focus.

It is well known as the pupil - a dark circular opening in the center of the iris of the eye, varying in size to regulate the amount of light reaching the retina, so that you can have a visual at the things you look at.

Also, if there are unknown, alien substances in your body, such as drugs, that is also a pupil dilator. Also, if you have recently suffered a concussion, your pupils might be dilated for a while. Pupils also dilate when focusing on different planes of vision, as well as different distances.
